Abstract

Background: Long Latency Auditory Evoked Potentials in children with sensorineural hearing loss. Objective: To compare the long latency auditory potentials in children with bilateral sensorineural hearing losses from mild to moderately severe with those obtained in normal hearing children of the same age group. Methods: Cross-sectional clinical study, consisting of two groups: control group - Group of 10 normal hearing children, 6-13 years of age, of both genders, Research Group - Group of 10 children with sensorineural hearing loss of mild to moderately severe bilateral symmetry between the ears, aged 6 to 13 years of age, of both genders, with no prior experience with any type of sound amplification device. Will be recorded Auditory Evoked Potential Long-Latency (LLAEP) to research complex waves P1-N1-P2 and P300 (Cognitive potential) and using speech stimuli presented in sound field system. Scientific contributions: It is necessary to identify differences between the patterns obtained from children with sensorineural hearing loss and the patterns obtained from normal hearing children, intending to assist in the selection and fitting of hearing aids, as well as assisting in the rehabilitation of these individuals.
